I'm looking to save work, not add more or replace one with the other. Plus I
have ZFS snapshots [1]. Either way, as long as I keep bdb libraries in sync on
the machines, my initial tests show this is working as I expected. Now I'll
just sit and wait for the corner cases where it won't work, but can't think of
any. ;)
